.Sh DESCRIPTION
These functions decode and encode X.509 structures used for the
time-stamp protocol.
For details about the semantics, examples, caveats, and bugs, see
.Xr ASN1_item_d2i 3 .
.Pp
.Fn d2i_TS_REQ
and
.Fn i2d_TS_REQ
decode and encode an ASN.1
.Vt TimeStampReq
structure defined in RFC 3161 section 2.4.1.
.Fn d2i_TS_REQ_bio ,
.Fn i2d_TS_REQ_bio ,
.Fn d2i_TS_REQ_fp ,
and
.Fn i2d_TS_REQ_fp
are similar except that they decode or encode using a
.Vt BIO
or
.Vt FILE
pointer.
.Pp
.Fn d2i_TS_RESP
and
.Fn i2d_TS_RESP
decode and encode an ASN.1
.Vt TimeStampResp
structure defined in RFC 3161 section 2.4.2.
.Fn d2i_TS_RESP_bio ,
.Fn i2d_TS_RESP_bio ,
.Fn d2i_TS_RESP_fp ,
and
.Fn i2d_TS_RESP_fp
are similar except that they decode or encode using a
.Vt BIO
or
.Vt FILE
pointer.
.Pp
.Fn d2i_TS_STATUS_INFO
and
.Fn i2d_TS_STATUS_INFO
decode and encode an ASN.1
.Vt PKIStatusInfo
structure defined in RFC 3161 section 2.4.2.
.Pp
.Fn d2i_TS_TST_INFO
and
.Fn i2d_TS_TST_INFO
decode and encode an ASN.1
.Vt TSTInfo
structure defined in RFC 3161 section 2.4.2.
.Fn d2i_TS_TST_INFO_bio ,
.Fn i2d_TS_TST_INFO_bio ,
.Fn d2i_TS_TST_INFO_fp ,
and
.Fn i2d_TS_TST_INFO_fp
are similar except that they decode or encode using a
.Vt BIO
or
.Vt FILE
pointer.
.Pp
.Fn d2i_TS_ACCURACY
and
.Fn i2d_TS_ACCURACY
decode and encode an ASN.1
.Vt Accuracy
structure defined in RFC 3161 section 2.4.2.
.Pp
.Fn d2i_TS_MSG_IMPRINT
and
.Fn i2d_TS_MSG_IMPRINT
decode and encode an ASN.1
.Vt MessageImprint
structure defined in RFC 3161 section 2.4.1.
.Fn d2i_TS_MSG_IMPRINT_bio ,
.Fn i2d_TS_MSG_IMPRINT_bio ,
.Fn d2i_TS_MSG_IMPRINT_fp ,
and
.Fn i2d_TS_MSG_IMPRINT_fp
are similar except that they decode or encode using a
.Vt BIO
or
.Vt FILE
pointer.
